[0038] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the pneumatic telescopic assembly includes a bearing base 201 and a multi-stage pneumatic telescopic cylinder 202;

[0039] The bottom end of the multi-stage pneumatic telescopic cylinder 202 is mounted on the bearing base 201 through a ball head seat module, and the top end of the multi-stage pneumatic telescopic cylinder 202 is connected to the side wall of the lifting plate 1 through a ball head seat module;

[0040] An air leakage hole 203 communicating with the inner cavity of the multi-stage pneumatic telescopic cylinder 202 is provided on the outer wall of the top end thereof. The air leakage hole 203 is communicated with the air inlet end of the telescopic air leakage cylinder assembly through a first connecting pipe 204 .

[0041] In this embodiment, the multi-stage pneumatic telescopic cylinder 202 is a three-stage pneumatic telescopic cylinder, which includes a bottom sleeve 2021, an intermediate sleeve 2022 and a top sleeve 2023. The top ends of the bottom sleeve 2021, the intermediate sleeve 2022 and the top sleeve 2023 are all provided with a cylinder cover, and the outer walls of the lower ends of the intermediate sleeve 2022 and the top sleeve 2023 are both provided with a first sealing ring. The ball head seat module of the multi-stage pneumatic telescopic cylinder 202 and the bearing base 201 includes a first ball head 209 installed on the bearing base 201, and a first ball head seat 210 installed at the bottom of the bottom sleeve 2021, and the first ball head seat 210 can rotate around the first ball head 209.

The second ball head seat 211 can rotate around the second ball head 101 .

[0042] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the counterweight assembly includes a counterweight rod 301 and a counterweight ball 302 installed at the bottom end of the counterweight rod 301, and the center of the counterweight ball 302 is located on the axis of the counterweight rod 301;

[0043] The top end of the counterweight rod 301 is connected to one end of the universal joint 303, and the other end of the universal joint 303 is installed on the lower end surface of the lifting plate 1. When the lifting plate 1 is set horizontally, the axis of the counterweight rod 301 coincides with the central axis of the lifting plate 1.

[0044] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the telescopic deflation cylinder assembly includes a mounting block 401 mounted on the lower end surface of the lifting plate 1, a piston sleeve 402 mounted on the mounting block 401 through a ball head seat module, and a piston rod 403 sealingly sliding along the piston sleeve 402;

[0045] The front end of the piston rod 403 is connected to the counterweight rod 301 through a ball head seat module, and an air inlet hole 404 connected to its inner cavity is opened on the outer wall of the rear end of the piston sleeve 402. A plurality of leakage holes 405 connected to its inner cavity are opened on the outer wall of the middle part of the piston sleeve 402. When the rear end face of the piston rod 403 extends forward and passes over a certain end face, the leakage holes 405 start to leak air. This end face is defined as the starting end face. When the lifting plate 1 is set horizontally, one end face of the piston rod 403 is flush with the starting end face.

[0046] In this embodiment, a second sealing ring 407 is sleeved on the outer wall of one end of the piston rod 403 in the piston sleeve 402. Initially, the second sealing ring 407 closest to the mounting block 401 is sealed against the starting end face.

[0047] In this embodiment, the ball head seat module between the piston rod 403 and the counterweight rod 301 includes a third ball head 406 installed on the top of the piston rod 403 and a third ball head seat 304 installed on the side wall of the counterweight rod 301, and the third ball head seat 304 can rotate around the third ball head 406.

[0048] In this embodiment, the ball head seat module between the piston sleeve 402 and the mounting block 401 includes a fourth ball head 408 mounted on the rear end of the piston sleeve 402 and a fourth ball head seat 409 mounted on the mounting block 401 .

[0049] like Figure 1 , Figure 2 and Figure 6 As shown, it also includes an air supply assembly, which includes a central mounting plate 501 and a plurality of charging and discharging air pumps 502 mounted on the central mounting plate 501;

[0050] The outer wall of the bottom end of the multi-stage pneumatic telescopic cylinder 202 is provided with air inlet and outlet ports 205 connected to its inner cavity, and the air charging and discharging ports 503 of the plurality of air charging and discharging pumps 502 are respectively connected to the plurality of air inlet and outlet ports 205 through the second connecting pipe 504 .

[0051] In this embodiment, there are three groups of charging and discharging air pumps 502, which respectively supply air to three groups of pneumatic telescopic components. The air supply components also include a brushless motor 508. The three groups of charging and discharging air pumps 502 are all driven by the brushless motor 508 to charge and discharge air.

[0052] like Figure 1 , Figure 2 and Figure 6 As shown, a plurality of clamping rings 505 for clamping a plurality of multi-stage pneumatic telescopic cylinders 202 are also installed on the outer wall of the central mounting plate 501, and the plurality of clamping rings 505 are arranged in an array at equal angles along the central axis of the central mounting plate 501;

[0053] The central mounting plate 501 and the supporting base 201 are connected via a connecting rod assembly.

[0054] like Figure 1 , Figure 2 and Figure 6 As shown, the connecting rod assembly includes a connecting rod 506 and a stabilizing tube 507 which are hinged to each other at one end;

[0055] The other end of the connecting rod 506 is hingedly mounted on the side wall of the central mounting plate 501 . A stabilizing tube mounting seat 206 is provided on the bearing base 201 , and the other end of the stabilizing tube 507 is mounted on the stabilizing tube mounting seat 206 .

[0056] like Figure 1 , Figure 2 and Figure 6 As shown, ground nail holes 207 are also opened at both ends of the bearing base 201. When the pneumatic lifting bracket is installed, the ground nails 208 are inserted into the ground nail holes 207 to lock it on the installation surface.

[0057] In this embodiment, when the bracket is stored, the bottom sleeve 2021 is clamped in the clamp ring 505 to prevent the multi-stage pneumatic telescopic cylinder 202 from shaking. When the bracket is unfolded, the bearing base 201, the ground nail 208, the connecting rod 506 and the stabilizing tube 507 are aligned with the unfolding angle for positioning.

[0058] The working principle of the utility model is as follows: when the bracket is installed, the bottom sleeve 2021 is removed from the retaining ring and unfolded, and the bearing base 201 is locked to the installation ground through the ground nail 208. The brushless motor 508 simultaneously drives three sets of charging and discharging air pumps 502 to fill equal amounts of gas into three sets of multi-stage pneumatic telescopic cylinders 202. When the bracket is installed on an inclined ground, the center of gravity of the equipment will be biased toward one or two sets of multi-stage pneumatic telescopic cylinders 202 with a lower installation position. Since the counterweight assembly is always vertically downward, it will pull the two higher sets or one group of piston rods 403, so that the leakage holes 405 of the two sets or one group are connected with the piston sleeve 402. When the center of gravity of the equipment coincides with the axis of the lifting plate 1, the lifting plate 1 is in a horizontal position, and one end face of the three piston rods 403 is aligned with the starting end face. The lifting plate 1 maintains a horizontal and stable state. Similarly, when the center of gravity of the equipment shifts under the action of external forces such as wind, the telescopic amount of one or two groups of multi-stage pneumatic telescopic cylinders 202 under heavy load is less than that of two or one group of multi-stage pneumatic telescopic cylinders 202 under light load, and the lifting plate 1 tilts. Since the counterweight assembly is always vertically downward, it will pull the two or one group of piston rods 403 on the lightly loaded side, so that the two or one group of air leakage holes 405 are connected with the piston sleeve 402. When the center of gravity of the equipment coincides with the axis of the lifting plate 1, the lifting plate 1 is in a horizontal position, and the end faces of the three piston rods 403 are all aligned with the starting end faces. The lifting plate 1 remains in a horizontal and stable state again, completing the adaptive leveling of the bracket.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the above embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the utility model can still be modified or replaced by equivalents, and any modification or equivalent replacement that does not depart from the spirit and scope of the utility model should be included in the scope of protection of the claims of the utility model.
